  • Patent number: 4271678
    Abstract: An economical energy-saving air-conditioning system for cooling air in an enclosure requiring year-around cooling. An outdoor heat exchanger is operative in a recirculating liquid closed-loop cooling system. A temperature controlled actuator provides continuous free cooling when the outside temperature is approximately 35.degree. to 40.degree. F. or less; and provides free pre-cooling of the air when the outside temperature is in the 35.degree. to 65.degree. F. range. The closed-loop comprises conventional components for summer temperature cooling; and, in less-than summer temperatures the present invention utilizes the outside heat exchanger to provide cool heat exchange liquid to a (free) cooling coil positioned to confront the air stream in advance of a refrigerant coil. Reheat for dehumidification is provided in an embodiment wherein thermal energy is taken from the waste heat of the refrigerant system.

  • Patent number: 4270362
    Abstract: Temperature and humidity electrical/electronic control circuits and apparatus to maintain a room at a constant temperature and humidity. The control system is adapted to an environmental condition controller for year-around cooling utilizing a liquid recirculating to an outside coil for free cooling or free reheat dehumidification. The controls provide a sequencing function to actuate one or more temperature and/or humidity conditioners in response to the degree and percentage of change. The circuit provides a ramp function signal for proportional control over an initial temperature range of free cooling and step controls over other predetermined temperature ranges. The circuit comprises a high fidelity ramp generator linearly responsive to the degree of temperature change up to a predetermined set point. A dehumidification signal is developed and fed to the same ramp generator to carry out air cooling to remove moisture.

  • Patent number: 4227188
    Abstract: An intrusion alarm system utilizes an inertially responsive sensor preferably present as a pendulum actuated reed switch. Logic circuits provided within the system provide, an efficient pulsating alarm at dual frequencies optimized for human recognition. In both arrangements, a unique dual delay arrangement is provided, one delay commencing with the arming of the device to permit adequate time for the setting of a sensing switch.

  • Patent number: 4222639
    Abstract: Apparatus is provided for testing subjects for fixation disparity. The apparatus includes a first sheet-like element having an opening therein which is spaced from the subject being tested. This opening defines the periphery of a target which is dimensioned to represent a fusion stimulus to the subject. Within the opening there are displayed a sequence of paired first and second discrete, parallel target elements which are mutually spaced and fixed a predetermined distance from each other along the parallel lengthwise extends thereof. A sequence of these element pairs are positioned in regularly spaced order about a movable carrier and presented sequentially at the opening in the course of testing. The angular subtense represented by the spacing of the elements is indicated upon the carrier and when the subject perceives that the elements are mutually aligned, a recordation of angular subtense is made and utilized for diagnostic purposes.

  • Patent number: 4152122
    Abstract: An improved system for producing methane-containing product gas by the hydrogasification process. With the system, solid municipal waste is comminuted and dried following which it is introduced to the lock hopper receivers for transference to an elongate hydrogasification reactor. Synthesis gas is introduced to a lower region of the reactor and the comminuted waste, including inorganic materials, is dried and converted to methane-containing product gas and char. The char is removed from the system by a variety of separation systems including cyclone separators or aspirators and the inorganic fractured waste materials pass through the reactor but are undamaged and in a sterile condition ideally suited for recovery. A gasification reactor is incorporated with the system which receives char from the process as well as oxygen to produce the synthesis gas utilized in the hydrogasification reactor.

  • Patent number: 4126857
    Abstract: Apparatus and system for monitoring sites for the presence of moisture or the collection of conductive liquids. Two housings are utilized with the apparatus to facilitate user convenience. A first of these housings, mounted at a location selected for easy access by the user, retains manually actuated switching, alarm components and batteries. This housing is electrically coupled with a second, smaller housing serving to encapsulate solid-state switching logic components and moisture detecting probes. Spurious R.F. noise is avoided within the system through the positioning of this solid state switching at the second housing in close adjacency with the probes. The probes are formed of a base material, one surface portion of which is covered with a noble metal, such as platinum. The remaining surfaces of the base are permitted to develop, in situ, a surface oxide which is immune to galvanic corrosive participation.
